2. Human male and female behavioral differences find analogies through the mammalian class of animals. The males tend to compete more aggressively; the female are more inclined to parenting.
3. The brains of men differ visibly from the brains of women in several ways--larger brains with more neurons for men--women have more gray matter.
[4.] The nuclei in the hypothalamus are larger in men. These nuclei have been linked to sexual behavior and aggressiveness.
[5.] Women's left and right hemispheres appear to be larger so that their brains may function more smoothly than men's.

Whoh!
what's all this?
No's 1 and 2 - This is historical nonsense from primitive times (most other mammals are still in the 'primitive' stage - we are trying to climb out of it!).
No. 3 - the neurons are 'in' the grey matter, you are talking 'apples, and oranges'!
No 4. - the nucleus is the core of a cell, and is unrelated to the size of the hypothalamus (which is, as you say, larger in men, and is thought to be the centre of the old reptilian ancestral brain which worked almost entirely on instinct, without the benefit of 'thought'!).
No 5. - larger than what?... each other, or mens, either of which is nonsense, as they can't be bigger than each other; one must exceed the other; or they can't be bigger than the male, simply because the male brain is larger, in general!
Please!
